The drop bar impacts a release rod and shears the retaining pin holding it in place which causes the rod to move down. This movement of the rod releases the firing piston. Hydrostatic pressure drives the firing piston down towards the percussion initiator. The firing pin located at the end of the firing piston strikes the percussion initiator which in turn detonates the gun assembly. As a safety feature, a minimum hydrostatic pressure is required on the firing piston when the drop bar impacts in order to operate.

The drop bar has a brass impression pad on the base of it which can be used to confirm impact with the release rod by identifying a familiar pattern on the impression. The upper end of the drop bar incorporates a standard slickline fishing neck.

There is also an option to utilize a direct impact firing head which does not require any hydrostatic pressure (no firing piston) to fire the gun assembly
